Your phone buzzes at 5:47 AM. Your head pounds, your throat feels like sandpaper, and the mere thought of getting dressed makes you want to crawl deeper under the covers. You know you need to email your boss, but what exactly should you say? How much detail is too much? How little is too little?
Crafting the perfect sick leave email doesn’t have to add stress to your already miserable day. The right message protects your professional reputation while giving you the space you need to recover. Whether you’re dealing with a sudden flu, a chronic condition flare-up, or a mental health day, your email sets the tone for how your absence will be perceived and managed.
The difference between a well-written sick leave email and a poorly constructed one can impact your relationships with colleagues, your workload when you return, and even your job security. Master this essential workplace skill and you’ll handle sick days with confidence and professionalism.
